Designed to cope with the additional requirements of the telecommunications industry, the MIT481 includes 50 V and 100 V range insulation testing as standard, plus higher voltages as required. In addition, the voltage detection test inhibit feature has been raised to 75 V (from 50 V), to allow testing of cables with coactivity coupled induced voltages, which would normally inhibit such testing with a 50 V protected instrument. Finally the MIT481 includes measurement of cable distance by capacitance, providing a convenient cable length without the need to use TDR technology, with adjustable cable capacitance from 40 nF/Km to 60 nF/Km (default is 50 nF/Km).
